[0073] The utility model provides a kind of cleaning system 1000, specifically, please refer to Figures 1 to 2 In the embodiment, the cleaning system 1000 includes cleaning equipment 100 and base station 200, the cleaning equipment 100 includes two roll brush pieces 1, at least one roll brush piece 1 is movably arranged, so that the cleaning equipment 100 has two roll brush pieces 1 and the first state of mutual approach, and has two roll brush pieces 1 and the second state of mutual separation;Base station 200 can be connected with cleaning equipment 100;Wherein, after cleaning equipment 100 and base station 200 are connected, cleaning equipment 100 is in the second state.

[0074] In the embodiment, the cleaning device 100 comprises two roller brush members 1, at least one of which is movably arranged, and the distance between the two roller brush members 1 can be adjusted by moving the at least one roller brush member 1, so that the cleaning device 100 can keep the two roller brush members 1 in a first state of being close to each other during normal operation, and the two roller brush members 1 can better and more completely cover the cleaning area, ensuring that there is no omission in the area cleaned by the cleaning device 100, and the cleaning effect is better. When the cleaning device 100 is finished cleaning, the cleaning device 100 can be docked with the base station 200, and the two roller brush members 1 can be adjusted to a second state of being away from each other. During the process of moving away from each other, the two roller brush members 1 can tear or loosen the hair and other filamentous objects wound thereon, thereby reducing the adhesion of the hair and other filamentous objects to the roller brush members 1, so that the base station 200 can more easily suck the hair and other filamentous objects off the roller brush members 1, and the filamentous objects on the roller brush members 1 are more easily cleaned. Moreover, during the cleaning process of the cleaning device 100, the working state of the two roller brush members 1 can also be switched intermittently, so that the filamentous objects on the roller brush members 1 are not wound too tightly, so as to be easily detached and sucked into the cleaning device 100, thereby ensuring the cleaning efficiency of the cleaning device 100, and the user does not need to manually clean the roller brush members 1 subsequently, which can effectively improve the user experience.

[0075] Preferably, the cleaning device 100 can be a sweeping robot, a scrubber, or a sweeping and mopping all-in-one machine, etc. For convenience of description, the following will mainly take a sweeping robot as an example for description, and other devices can be adapted accordingly.

[0076] It should be noted that, as shown in Figure 2 The cleaning device 100 can also comprise a device body 4, and the two roller brush members 1 are arranged on the device body 4. When the cleaning device 100 normally performs cleaning work, the forward direction of the cleaning device 100 is the front of the device body 4, and the backward direction of the cleaning device 100 is the rear of the device body 4. The following description of the orientation can be based on this.

[0077] It can be understood that the rotation axes of the two roller brush members 1 of the cleaning device 100 preferably extend along the left-right direction of the cleaning device 100 or are arranged in an inclined manner along the left-right direction of the cleaning device 100, so that when the cleaning device 100 moves forward or backward, the rotation direction of each roller brush member 1 can better follow the direction in which the device body 4 moves forward or backward, the resistance to movement is less, and the dirt on the surface to be cleaned (such as the ground) can be better rolled up by the roller brush members 1. However, the relative arrangement direction of the two roller brush members 1 can be various.

[0078] In an embodiment, the two rolling brush members 1 are arranged in a spaced manner along the front-rear direction of the cleaning device 100, so that the length of each rolling brush member 1 (i.e. the length along the left-right direction of the cleaning device 100) can be set longer, the cleaning area is larger, and the front-rear rolling brush members 1 can repeatedly clean the ground, which can effectively improve the cleaning effect. At this time, the two rolling brush members 1 can have a moving stroke of moving closer to each other or moving away from each other along the front-rear direction, so as to adjust the distance between the two rolling brush members 1 along the front-rear direction of the cleaning device 100, and the distance between the two rolling brush members 1 can be increased to tear the hair on each rolling brush member 1, so that the hair does not excessively entangle on each rolling brush member 1, and the cleanliness of each rolling brush member 1 is ensured, thereby ensuring the cleaning effect of the cleaning device 100.

[0079] Preferably, as shown in Figure 2 and Figure 4 , the rotating shafts of the two rolling brush members 1 are arranged along the same line, i.e. preferably the rotating shafts of the two rolling brush members 1 are arranged along the left-right direction of the cleaning device 100 in sequence. When the two rolling brush members 1 move closer to each other to be in the first state, the two rolling brush members 1 jointly cover the cleaning area, and the cleaning areas of the two rolling brush members 1 jointly form the cleaning area of the cleaning device 100.

[0080] It can be understood that the adjustment of the distance between the two rolling brush members 1 can be realized by the movement of one of the rolling brush members 1. Alternatively, both of the rolling brush members 1 can be moved, so that the adjustment of the distance between the two rolling brush members 1 is more flexible and convenient.

[0081] Preferably, both of the rolling brush members 1 are movably arranged, and the moving strokes of the two rolling brush members 1 are consistent, and each rolling brush member 1 has a moving stroke along the transverse direction of the cleaning device 100. Specifically, as shown in Figure 3 , the rotating shafts of the rolling brush members 1 extend along the transverse direction of the cleaning device 100, and the two rolling brush members 1 are oppositely arranged along the transverse direction of the cleaning device 100, and the two rolling brush members 1 are simultaneously moved oppositely to move closer to each other to be in the first state, or the two rolling brush members 1 can be simultaneously moved oppositely to move away from each other to be in the second state. Without changing the original volume of the cleaning device 100, the cleaning efficiency of the cleaning device 100 can be better, and the filament is not easy to entangle on each rolling brush member 1. Here, the transverse direction can refer to one of the directions along the horizontal plane, and the longitudinal direction is perpendicular to the transverse direction in the horizontal plane. Preferably, the transverse direction is along the left-right direction of the cleaning device 100, and the longitudinal direction is along the front-rear direction of the cleaning device 100.

[0082] In the cleaning device 100, each of the two roller brush members 1 has a connecting end and a free end arranged oppositely along the axial direction of the roller brush member 1, the connecting end is used to connect with the device body 4, and the free end is arranged in a cantilevered manner. The free ends of the two roller brush members 1 are arranged oppositely along the transverse direction of the device body 4. The cleaning device 100 has a first state in which the free ends of the two roller brush members 1 are close to each other, and a second state in which the free ends of the two roller brush members 1 are away from each other after being connected with the base station 200.

[0083] It can be understood that the cleaning device 100 can further include a cleaning driving component, the two roller brush members 1 are driven to rotate by the cleaning driving component, so that the two roller brush members 1 can normally perform the cleaning work when being in the first state, and at the same time, the two roller brush members 1 can rotate in the same direction or in the opposite direction when the two roller brush members 1 are switched from the first state to the second state, so that the filaments can be better released from the roller brush members 1.

[0084] In an embodiment, in combination with Figure 4 and Figure 5 When being in the first state, the two roller brush members 1 have at least partially overlapped orthographic projections along the longitudinal direction of the cleaning device 100. That is, at least part of the two roller brush members 1 are arranged oppositely along the front-rear direction of the cleaning device 100, and there is no gap in the area cleaned by the two roller brush members 1 along the transverse direction of the cleaning device 100, so that there is no cleaning omission area in the cleaning area formed by the cleaning device 100 when performing the cleaning, the two roller brush members 1 can better cover the area to be cleaned, and the completeness of the cleaning is ensured.

[0085] Further, as shown in Figure 4 and Figure 6 The end faces of the free ends of the two roller brush members 1 are arranged obliquely along the transverse direction of the cleaning device 100 and are matched with each other, so that the two roller brush members 1 can be better overlapped when being in the first state, and a better cleaning effect is ensured.

[0086] Moreover, when in the first state, the end faces of the free ends of the two rolling brush members 1 are spaced apart, so that when the two rolling brush members 1 are working, no interference is formed, and each rolling brush member 1 can be moved and rotated independently. For example, when in the first state, the rotating directions of the two rolling brush members 1 can be consistent, so as to be more matched with the advancing direction of the cleaning device 100 and better perform the cleaning work. Alternatively, the rotating directions of the two rolling brush members 1 are opposite, so that the tearing effect on the filaments wound on the two rolling brush members 1 is better, the filaments on one rolling brush member 1 can be better dragged away by the other rolling brush member 1, and the filaments on the two rolling brush members 1 are easily loosened, so as to be easily sucked into the dust box inside the cleaning device 100 by the cleaning device 100. Still alternatively, one of the two rolling brush members 1 is set to rotate intermittently in the switching direction, so that the two rolling brush members 1 can better perform the cleaning work while the wound filaments are timely removed, the cleanliness of each rolling brush member 1 is better ensured, and the cleaning effect of each rolling brush member 1 is improved.

[0087] In another embodiment, as shown in Figure 8 In another embodiment, as shown in

[0088] Specifically, each rolling brush member 1 comprises a rolling brush cylinder and bristles arranged on the outer circumferential side of the rolling brush cylinder. Preferably, when in the first state, the spacing between the two rolling brush members 1 in the transverse direction of the cleaning device 100 is 2mm-6mm, so that there is a certain gap between the rolling brush cylinders of the two rolling brush members 1, but the distance between the gaps cannot be too large, and the flexible bristles on the two rolling brush members 1 can cover the gap area, so that a cleaning omission area is avoided; the distance between the two rolling brush members 1 also cannot be too small, so as to avoid interference when the rolling brush members 1 are loosened.

[0089] Moreover, when the two rolling brush members 1 each have an activity stroke in the left-right direction of the cleaning device 100, preferably, the cleaning device 100 can comprise two sets of driving structures 2, the two sets of driving structures 2 are connected to the two rolling brush members 1 one by one and are used to drive the two rolling brush members 1 to switch between the first state and the second state, and each driving structure 2 can drive the corresponding rolling brush member 1 to move, so that the adjustment of the two rolling brush members 1 is more flexible, and the cleaning of the filaments is also more flexible and effective.

[0090] Specifically, there are various ways to drive the two roller brushes 1 to move along the left and right directions of the cleaning device 100. In one embodiment, each drive structure 2 includes a first driver and a first transmission; wherein, the first driver can be configured as a drive motor; the first transmission member 23 connects the corresponding first driver and the corresponding roller brush 1, and the first transmission member 23 is screwed into the corresponding roller brush 1; the two first drivers drive the corresponding two first transmission members 23 to rotate forward or backward, thereby driving the two roller brushes 1 to switch between a first state and a second state. By driving the corresponding first transmission member 23 to switch the rotation direction by the first driver, the corresponding roller brushes 1 can be driven to move along the left and right directions of the cleaning device 100.

[0091] Preferably, such as Figure 9 As shown, each first transmission component 23 is configured as a threaded rod 231, and the rotation shaft of each roller brush 1 is screwed to the corresponding threaded rod 231. In the first state, the two first drivers drive the two first transmission components 23 to rotate clockwise, allowing the two roller brushes 1 to rotate clockwise together. When the two first drivers drive the two first transmission components 23 to rotate counterclockwise, the two roller brushes 1 move in opposite directions to switch to the second state. Clockwise rotation refers to rotation along the rotation shaft of the roller brush 1 in a clockwise direction, while counterclockwise rotation refers to rotation along the rotation shaft of the roller brush 1 in a counterclockwise direction. Conversely, if clockwise rotation is counterclockwise rotation along the rotation shaft of the roller brush 1, then counterclockwise rotation is clockwise rotation along the rotation shaft of the roller brush 1.

[0092] In this embodiment, the first driver forms the cleaning drive component described above. In the first state, when the first driver drives the first transmission member 23 to rotate continuously in the forward direction, each first transmission member 23 and the corresponding roller brush member 1 are in a screw-locked state. Therefore, the forward rotation of the first transmission member 23 can drive the corresponding roller brush member 1 to rotate in the forward direction, and the two roller brush members 1 can perform cleaning work normally at this time. When the first driver drives the first transmission member 23 to switch from forward rotation to reverse rotation, the first transmission member 23 and the corresponding roller brush member 1 are unlocked, so that each roller brush member 1 can move along the corresponding threaded rod 231, thereby moving the two roller brush members 1 away from each other and realizing the cleaning of filamentous materials on the two roller brush members 1.

[0093] Similarly, when in the second state, the two first drivers drive the two first transmission members 23 to reverse, thereby driving the two roller brush members 1 to reverse together. When the two first drivers drive the two first transmission members 23 to rotate forward, the two roller brush members 1 move towards each other to switch to the first state. The same principle as in the first state, when in the second state, the roller brush members 1 and the corresponding first transmission members 23 are locked in reverse. By driving the two first transmission members 23 to reverse through the two first drivers, the two roller brush members 1 can be driven to reverse together, so that the cleaning equipment 100 in the second state can also continue to rotate. When the first driver drives the corresponding first transmission member 23 to rotate forward, the first transmission member 23 and the corresponding roller brush member 1 are unlocked, and the roller brush member 1 can move relative to the threaded rod 231. The two roller brush members 1 can move towards each other to be in the first state.

[0094] In another embodiment, in combination with Figure 5 and Figure 7 It is shown that each driving structure 2 includes a second driver 21 and a second transmission member 22. The second driver 21 can also be provided as a driving motor. The second transmission member 22 is connected to the corresponding second driver 21 and the corresponding roller brush member 1. Each second driver 21 drives the corresponding second transmission member 22 to move in the transverse direction of the cleaning equipment 100, thereby driving the two roller brush members 1 to move towards or away from each other. The two roller brush members 1 can move in the transverse direction of the cleaning equipment 100 in a translational manner, and the movement stroke is easier to adjust and control.

[0095] Preferably, as shown in Figure 5 and Figure 7 It is shown that the second transmission member 22 includes a screw rod 221 and a nut 222 in screw connection, and a transmission frame 223 connected to the roller brush member 1. The nut 222 is arranged on the transmission frame 223. Each second driver 21 drives the corresponding screw rod 221 to rotate, thereby driving the nut 222 to move along the corresponding screw rod 221, and driving the corresponding transmission frame 223 and the roller brush member 1 to move together. The screw rod 221 and the nut 222 structure can make the movement of the roller brush member 1 in the transverse direction more accurate, and the noise during adjustment is smaller, so that the noise of the cleaning equipment 100 during work is smaller.

[0096] In this embodiment, the cleaning device 100 further includes two third drivers 3, which form the aforementioned cleaning drive components. Each of the two third drivers 3 is connected to one of the two roller brushes 1, respectively, to drive the two roller brushes 1 to rotate. The two third drivers 3 are mounted on corresponding transmission frames 223. By driving the two roller brushes 1 to rotate via the two third drivers 3, the two roller brushes 1 can perform rolling cleaning. Furthermore, by mounting the two third drivers 3 on the two transmission frames 223, the two third drivers 3 can move together when the two roller brushes 1 move, ensuring that each roller brush 1 can rotate at any position between the first and second states, thus achieving better cleaning effects at different positions.

[0097] In another embodiment of the drive structure 2, each drive structure 2 may include an electromagnet, an electromagnetic relay, and an elastic element. The electromagnet is located at one end of the two roller brushes 1 that are positioned opposite each other. The electromagnet may be made of a magnetically attractive material. The electromagnetic relay is positioned opposite the electromagnet. When the electromagnetic relay is energized, it magnetically attracts the corresponding electromagnet, thereby moving the two roller brushes 1 in a direction away from each other. The elastic element connects the roller brushes 1 and the cleaning device 100. The elastic element is configured as a telescopic spring. When the electromagnetic relay is magnetically attracted to the electromagnet, the two roller brushes 1 are far apart and in a second state, and the elastic element is in an elastic energy storage state. When the electromagnetic relay is de-energized, the two roller brushes 1 move closer together under the elastic restoring force of the elastic element and are in a first state. By controlling the on / off state of the electromagnetic relay, the two states of the roller brushes 1 can be switched.

[0098] The driving structure 2 can be configured in various ways, including but not limited to those described above. Furthermore, the driving structure 2 can be configured in a combination of two or more of the above methods, which will not be detailed here.

[0099] The cleaning device 100 also includes a cleaning port located at the bottom of the main body 4. The cleaning port exposes at least a portion of the two roller brushes 1, allowing the roller brushes 1 to better contact the surface to be cleaned. In the first state, the connecting ends of the two roller brushes 1 are aligned with or retracted into the cleaning port along the lateral direction, meaning the two roller brushes 1 can completely cover the area of ​​the cleaning port. This allows the roller brushes 1 of the cleaning device 100 to occupy a larger cleaning area and achieve higher cleaning efficiency.

[0100] Moreover, such as Figure 10 As shown, the cleaning device 100 also includes a limiting structure 41, which limits the travel of the two roller brushes 1 so that the two roller brushes 1 can be better maintained in the first state and the second state.

[0101] The cleaning device 100 further comprises a roller brush cover arranged on the outer circumferential side of the two roller brush members 1, and a bottom cover arranged on the bottom of the device main body 4, the bottom cover being connected with the roller brush cover. The transmission frame 223 is slidingly arranged in the roller brush cover, and the roller brush cover is formed with a limiting groove 411, at least part of the transmission frame 223 being slidingly arranged in the limiting groove 411, and one end of the limiting groove 411 being open. At least part of the bottom cover is arranged to block the open side of the limiting groove 411. The limiting structure 41 is formed by the limiting groove 411 and the bottom cover, and the movement stroke of the transmission frame 223 in the left-right direction of the cleaning device 100 is limited, so as to limit the movement stroke of the two roller brush members 1.

[0102] In an embodiment, the cleaning device 100 further comprises a detection structure for detecting the state of the two roller brush members 1, so as to better control the operation of the driving structure 2. Furthermore, the cleaning device 100 can further comprise a controller electrically connected with the detection structure and the driving structure 2. The position detection result of the two roller brush members 1 is sent to the controller through the detection structure, and the corresponding driving structure 2 can be controlled to work through the controller, so as to better realize the automatic adjustment of the two roller brush members 1, and make the operation of the cleaning device 100 more intelligent.

[0103] When the cleaning device 100 is docked with the base station 200, the position state of the two roller brush members 1 can also be detected through the detection structure. When the two roller brush members 1 are in the second state, the driving structure 2 can be controlled not to work. When the detection structure detects that the two roller brush members 1 are in the first state, the controller can control the driving structure 2 to work, so as to drive the two roller brush members 1 to move away from each other to enter the second state, and then start the cleaning work of the cleaning device 100 by the base station 200.

[0104] The cleaning equipment 100 in the embodiment can be the cleaning equipment 100 in the above embodiment, or can be other cleaning equipment 100 different from the above embodiment. Specifically, the cleaning equipment 100 comprises a device main body 4 and two roller brush pieces 1, and the two roller brush pieces 1 are movably arranged on the device main body 4. The two roller brush pieces 1 are movably relative to each other, so that the cleaning equipment 100 has a first cleaning mode in which the two roller brush pieces 1 are close to each other and a second cleaning mode in which the two roller brush pieces 1 are away from each other. In the first cleaning mode, the two roller brush pieces 1 are in a first state in which they are close to each other, and the cleaning equipment 100 can normally perform cleaning work. In the second cleaning mode, the two roller brush pieces 1 are in a second state in which they are away from each other, and the cleaning equipment 100 can clean the hair wound on each roller brush piece 1, or can realize special track type cleaning, such as cleaning of a groove structure, and the like. Through switching between the first cleaning mode and the second cleaning mode, the cleaning equipment 100 has more diversified functions, and the roller brush piece 1 is more easily cleaned, and the working efficiency is also higher.

[0105] The above is only the preferred embodiment of the utility model, and does not limit the patent range of the utility model, and equivalent structures made by using the contents of the utility model specification and drawings, or directly or indirectly used in other related technical fields, are also included in the patent protection range of the utility model.
